Tarantino has said he'd never do a superhero comic because the fans obsess over casting or the color red in Superman's cape.

That's true, look at the reaction to Tarantino's remarks. Too many fans with too much time on their hands. And I am so sick of the constant excuse for every comic book character, "it's never been done right on the big screen". With decades of films behind some of these characters if they haven't been done right yet then it will never be.
